MT46V32M16P-6T IT:F TR

The MT46V32M16P-6T IT:F TR is a 512 Mbit DDR SDRAM organized as 32M × 16 with a parallel memory interface in a 66‑pin TSSOP package. It implements a double-data-rate architecture with internal DLL and source‑synchronous DQS for high‑throughput memory transfers.

Designed for systems that require 512 Mbit of volatile DDR memory in a space-efficient 66‑TSSOP footprint, the device offers programmable burst lengths, differential clock inputs, and industrial operating temperature support for robust operation across -40°C to +85°C.

Key Features

• Memory Architecture 512 Mbit DDR SDRAM organized as 32M × 16 with four internal banks and support for programmable burst lengths of 2, 4, or 8.
• Performance Double‑data‑rate operation with two data transfers per clock cycle; rated clock frequency up to 167 MHz (CL = 2.5 timing grade -6T) and an access time specification of 700 ps.
• Interface Parallel memory interface with bidirectional data strobe (DQS) transmitted/received with data; x16 devices include two DQS lines (one per byte) and two data mask (DM) signals.
• Clock and Timing Differential clock inputs (CK, CK#), commands sampled on CK positive edge, DQS alignment with data for READs and WRITEs, and an internal DLL to align DQ/DQS with CK.
• Refresh and Self‑Maintenance Supports auto refresh (8192 cycles for standard commercial/industrial refresh intervals) and selectable self refresh options (self refresh not available on AT devices as specified).
• Power 2.3 V to 2.7 V supply range (VDD and VDDQ operating nominally at 2.5 V ± tolerance options indicated in datasheet).
• Package 66‑TSSOP (0.400", 10.16 mm width) plastic package option; longer‑lead TSOP available for improved reliability as noted in product documentation.
• Temperature Range Industrial temperature rating: −40°C to +85°C (TA).
• Write and Cycle Timing Word/page write cycle time specified at 15 ns; timing grades include the -6T speed grade targeting DDR333 operation.

Typical Applications

• Parallel DDR Memory Subsystem Use as a 512 Mbit parallel DDR SDRAM device where a 32M × 16 organization and x16 data path are required for system memory implementations.
• Industrial Embedded Systems Industrial temperature rating (−40°C to +85°C) makes the device suitable for embedded designs demanding temperature‑tolerant volatile DDR storage.
• Board‑level Upgrades and Replacements Available in a 66‑TSSOP footprint for designs targeting through‑hole-compatible TSOP placement or retrofit scenarios requiring this package geometry.

Unique Advantages

• DDR Source‑Synchronous Interface: DQS transmitted/received with data and an internal DLL enable source‑synchronous capture for reliable high‑speed transfers.
• Byte‑wise Control for x16: Two DQS and two DM signals on the x16 device provide per‑byte data strobe and write masking for finer control of write operations.
• Flexible Timing Options: Available speed grades (including -6T) and programmable burst lengths (2, 4, 8) allow tuning of throughput and latency to match system timing requirements.
• Industrial Temperature Support: Rated for −40°C to +85°C operation, enabling use in temperature‑sensitive embedded and industrial environments.
• Compact TSOP Packaging: 66‑pin TSSOP package (10.16 mm width) supports compact board layouts while retaining parallel DDR connectivity and full feature set.

Why Choose MT46V32M16P-6T IT:F TR?
